I agree that rebases are currently very frustrating for reviewers and
that you've spelled out the root problems. I suggest to

1. Fix gerrit to generate useful interdiffs between patchsets that hide
unrelated changes between the base revisions. As Olivier points out I've
done that in https://github.com/ckamm/gerrit/tree/interdiff-stable-2.8.

2. Use a smarter version of the trivial rebase script to propagate
reviews to new patchsets. Ideally that'd use the better diffs gerrit
emits for its decision. I haven't done that.

My implementation of 1 is a hack, definitely not perfect and doesn't
work at all with gerrit's new change screen yet. But it's worked well
for me on top of gerrit 2.8 for more than a year. If Digia/QtCompany is
interested, I may be able to help out with integration or any further
fixes that become necessary in that area.
